This should do it: (i hope) /(\S|\s)*\bethyl\b(\S|\s)*/i -- dd

For example, for all words starting with "ethyl": a) replace "ethyl" by "<b>ethyl</b>" b) replace "Ethyl" by "<b>Ethyl</b>" c) replace "ethylene" by "<b>ethylene</b>" d) but not "methyl" by "<b>methyl</b>" Now I use: $patterns[0] = "/ethyl/"; $replacements[0] = "<b>ethyl</b>"; $text = preg_replace($patterns, $replacements, $text); This works for a) and c), but not for b) and d). Any idea how to do this ? TIA, Cor

Thanks Deniz, I tried pattern /^ethyl/i but this does not highlight anything. I also tried pattern /ethyl/i and this highlights all, but also methyl ... Any suggestion ? Cor Hi Deniz, I tried the referred regex tool as well, and I get Bad Result for /^ethyl/i and Good Result for /ethyl/i Cor Hi Deniz, Edward, Mike,

Thanks for your suggestions. Deniz, pattern /(\S|\s)*\bethyl\b(\S|\s)*/i makes from any line containing ethyl, such as Undenatured ethyl alcohol lines containing only: >ethyl Edward, pattern /(\s|>)ethyl(\s|<)/i makes from: Undenatured ethyl alcohol Undenaturedethylalcohol (stripping spaces). I will take a look at http://suda.co.uk/projects/SEHL/. Mike, the \W character makes from Undenatured ethyl alcohol Undenaturedethylalcohol (stripping spaces). The \b character makes: Undenatured ethyl alcohol (okay) the word methyl is unchanged (okay) but ethylene keeps also unchanged ... Thanks anyway ! Cor
